Buildings look pretty good, perhaps more contrast in the shadows to add some depth.
Your letting the render by the foreground textures. Orange stone, clearly tiles and very saturated. Also the road texture is odd… Perhaps too big. Sort these issues or perhaps a cunning crop to save time if your on a deadline
